Abstract
Abstract In an optical printer head or image reading apparatus, light emitting diodes, photo detectors and other picture elements are formed, by a specified number of pieces individually, as picture element arrays, and these arrays are linearly arranged. The distance of the picture elements at the adjacent outermost positions of the arrays, that is, the distance between the arrays, and the position of the heightwise direction of the arrays must be composed to be identical. Accordingly, the positioning marks are formed in the arrays in the same manufacturing process of the picture elements, and the distance between the arrays is adjusted at high precision. The arrays are affixed to the wiring substrate with an adhesive, and at this time by adjusting the layer thickness of the adhesive, the positions in the heightwise direction of the array surface are identically controlled. This job is done by adjusting the relative positions of the arrays to be mounted and the wiring substrate, while monitoring the wiring substrate on which the arrays are mounted, by a television camera or the like from the array side surface.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
64 words
At least one array of light emitting devices comprising: plural light emitting regions formed at constant intervals along a predetermined linear arranging direction, and reference regions possessing the same composition as the light emitting regions, and also having predetermined positions relative to the light emitting regions, the reference regions providing a basis for determining a distance between adjacent arrays of the light emitting devices.
Claim 2
Dependent Claim
64 words
At least one array of light emitting devices comprising: plural light emitting regions formed at constant intervals along a predetermined linear arranging direction, and reference regions possessing the same composition as the light emitting regions, and also having predetermined positions relative to the light emitting regions, the reference regions providing a basis for determining a distance between adjacent arrays of the light emitting devices.
Claim 3
Dependent Claim
74 words
At least one array of light emitting devices according to claim 1, further including connecting terminals connected to the light emitting regions, the connecting terminals being aligned and formed parallel to the linear arranging direction of the light emitting regions, and wherein the reference regions are shaped differently from the light emitting regions and connecting terminals and are formed at opposite ends of the linear arrangement of the light emitting regions and connecting terminals.
Claim 4
Independent Claim
117 words
A device for printing in which plural arrays of light emitting devices are disposed adjacently, wherein each array comprises: plural light emitting regions formed at constant intervals along a predetermined linear arranging direction, and reference regions possessing the same composition as the light emitting regions, and having predetermined positions relative to the light emitting regions, in which the spacing between neighboring reference regions formed in adjacent arrays is determined so that an interval comprising the distance between a light emitting region formed at the end of one array and a neighboring light emitting region formed at the end of an adjacent array is equal to the constant intervals between adjacent light emitting regions on the same array.
Claim 5
Independent Claim
